An upper ridge will become established over the central CONUS as a mid-level trough and associated upper support overspreads the Interior West tomorrow (Sunday). Stronger flow aloft mixing down to the surface via boundary-layer mixing by afternoon peak heating will support dry and windy conditions that support wildfire spread. The best chance for Critical conditions will be over southeastern Nevada into western Utah, where 20+ mph sustained southwesterly surface winds will coincide with 5-15 percent RH and at least modestly receptive fuels for several hours. Meanwhile, at least isolated thunderstorm development is expected ahead of a surface cold front accompanying the mid-level trough over northeast California into southwestern Idaho. Though a mix of wet and dry storms are possible, stronger mid-level flow aloft suggests these storms should move quickly eastward, with minimal precipitation accumulations. Given drying fuels in this region, lightning-induced wildfire ignitions are possible, necessitating the introduction of isolated dry thunderstorm highlights. ...Please see www.spc.noaa.gov/fire for graphic product... $$
